Elbaph Arc

The thirty-third story arc carries the crew, now accompanied by Lilith, Kuma, Bonney, and the giants of the Giant Warrior crew, to Elbaph, the fabled land of giants. There Robin is reunited with Jaguar D. Saul, and Luffy encounters the imprisoned and reviled prince Loki. As the tale unfolds, the history of the previous king Harald, his bond with Rocks D. Xebec, and the full truth behind God Valley come to light. Meanwhile, reeling from Vegapunk's broadcast, several major crews scramble after the One Piece, and the Knights of God mobilize to annex the giants' homeland for the World Government.

Sailing toward Elbaph, the crew read that fresh bounties had been posted for Dorry and Brogy after a century, and that the papers pinned Vegapunk's death on Luffy. Upon arrival, several Straw Hats found themselves trapped in a bizarre diorama ruled by a giant named Road, whom they escaped with Nami's lightning. Luffy dropped to the mainland and discovered Loki chained to the Treasure Tree Adam in the Underworld, branded the murderer of his father. Loki offered information about Shanks in exchange for his freedom. In the village, Robin tearfully embraced Saul, who had survived the Buster Call, and the crew learned that Harald had reshaped Elbaph toward diplomacy and education rather than warfare. An ancient text known as the Harley described two prior apocalypses that had befallen the world, both linked to the Sun God Nika, along with a third reckoning still to come.

The Knights of God, including Shamrock, Gunko, Sommers, and Killingham, invaded to seize the giant children and press Elbaph into the government's service ahead of a foretold Great War. Shamrock, revealed as Shanks' twin brother, impaled Loki, while the pirate legend Scopper Gaban emerged from hiding to aid the fight. A sprawling flashback laid out the truth: Harald had befriended Rocks D. Xebec, secretly a descendant of Davy D. Jones, but ended their friendship under the Five Elders' orders. At the God Valley Incident, Rocks sought to rescue his wife and infant son, only for Imu to turn him into a demon, and Roger and Garp together brought him down. Harald later became a Knight of God, but Imu's Depths Covenant commanded him to enslave his own people. Losing his mind, Harald forced Loki to consume Elbaph's treasured Devil Fruit and strike him dead, an act that Loki concealed even at the cost of the world's hatred.

In the present, Hajrudin freed Loki after learning the truth, and Loki transformed into the legendary beast Nidhoggr. As the Knights used the children's nightmares as weapons and turned the Giant Warrior Pirates into demons, the Straw Hats and their allies fought back. Luffy and Bonney, Chopper's strange curse-breaking ability, and the giants themselves turned the tide, until Imu personally descended upon Elbaph as the King of the World, wielding the Akuma no Mi. Luffy and Loki clashed with the ruler, driving off his shadowy form, while Brook uncovered that Gunko was in fact Princess Shuri from his living years, tied to the fall of his homeland Esperia. The battle for Elbaph continued as the truth of Harald's murder was broadcast across the island and Jarul declared that the giants would stand against the government once war arrived.

The arc reintroduced Saul, Jarul, and Gaban in the present, reunited Robin with her old protector, and gave Imu's face and identity as Saint Nerona Imu, one of the First Twenty. It exposed the Rocks Pirates' exploits, confirmed Shanks and Shamrock as sons of Figarland Garling, and unveiled the God Valley Incident in full, including Rocks' true name Davy D. Xebec and his fatherhood of Blackbeard. Loki's innocence in Harald's death was cleared, the Knights of God and their covenant-bound powers were detailed, and Elbaph aligned itself against the government ahead of the coming Great War. As an ongoing arc, its consequences continue to reshape the Final Saga.
